Corrosion engineering
sigma phase
Materials science; Corrosion engineering
A hard, brittle, nonmagnetic intermediate phase with a tetragonal crystal structure, containing 30 atoms per unit cell, space group P4 2 mnm, occurring in many binary and ternary alloys of the ...
depolarization
Materials science; Corrosion engineering
A decrease in the polarization of an electrode; the elimination or reduction of polarization by physical or chemical means; depolarization results in increased corrosion.
heat check
Materials science; Corrosion engineering
A pattern of parallel surface cracks that are formed by alternate rapid heating and cooling of the extreme surface metal, sometimes found on forging dies and piercing punches. There may be two sets ...
reduction
Materials science; Corrosion engineering
A reaction in which there is a decrease in valence resulting from a gain in electrons. Contrast with oxidation.
anodic inhibitor
Materials science; Corrosion engineering
A chemical substance or combination of substances that prevent or reduce the rate of the anodic or oxidation reaction by a physical, physico-chemical or chemical action.
diffusion coefficient
Materials science; Corrosion engineering
A factor of proportionality representing the amount of substance diffusing across a unit area through a unit concentration gradient in unit time.
cold cracking
Materials science; Corrosion engineering
A type of weld cracking that usually occurs below 203C (400F). Cracking may occur during or after cooling to room temperature, sometimes with a considerable time delay. Three factors combine to ...
